mrs.crw:That would be cute. I have these suede ankle boots.. I love them, but the color is weird. It's like a greyish with a purply hue. So IMO they wouldn't look right with grey.. I don't know, maybe they would look good with black. I am so challenged when it come to fashion lol.
Not sure what the boots look like but if I am imagining them correctly, what if you wore them with black tights and a black sweater dress and silver jewelry to pick up on the grey? I have seen this outfit before and it's cute. Some people might not want to wear black as their major color to a wedding, though.
Grey looks really good with purples/plums, too... and I also think it's cute with brown (though some people don't agree with me haha).
